This announcement is not for release, publication, distribution, directly or indirectly, in or into the United States (including its territories and possessions, any state of the United States and the District of Columbia). This announcement does not constitute or form a part of any offer or solicitation to purchase or subscribe for securities in the United States or in any other jurisdiction.

There will be no public offer of the Offer Shares in the United States.

In connection with the Global Offering, Goldman Sachs (Asia) L.L.C., as stabilizing manager (the “Stabilizing Manager”), its affiliates or any person acting for it, on behalf of the Underwriters, may effect transactions with a view to stabilizing or supporting the market price of the Shares at a level higher than that which might otherwise prevail for a limited period after the Listing Date. However, there is no obligation on the Stabilizing Manager, its affiliates or any person acting for it to conduct any such stabilizing action, which, if commenced, will be done at the absolute discretion of the Stabilizing Manager and may be discontinued at any time. Any such stabilizing activity is required to be brought to an end within the 30th day of the last day for lodging of applications under the Hong Kong Public Offering. Such stabilization action, if taken, may be effected in all jurisdictions where it is permissible to do so, in each case in compliance with all applicable laws, rules and regulatory requirements, including the Securities and Futures (Price Stabilizing) Rules (Chapter 571W of the Laws of Hong Kong), as amended, made under the Securities and Futures Ordinance (Chapter 571 of the Laws of Hong Kong).

Potential investors should be aware that stabilizing action cannot be taken to support the price of the Shares for longer than the stabilization period which begins on the Listing Date and is expected to expire on Friday, August 6, 2021, being the 30th day after the last day for lodging applications under the Hong Kong Public Offering. After this date, no further stabilizing action may be taken, and demand for the Shares and the price of the Shares could fall.

Potential investors of the Offer Shares should note that the Joint Global Coordinators (for themselves and on behalf of the Hong Kong Underwriters) shall be entitled to terminate their obligations under the Hong Kong Underwriting Agreement with immediate effect upon the occurrence of any of the events set out in the paragraph headed “Underwriting — Underwriting Arrangements and Expenses — Hong Kong Public Offering — Grounds for Termination” in the Prospectus at any time prior to 8:00 a.m. (Hong Kong time) on the Listing Date (which is currently expected to be on July 16, 2021).

THE LISTING APPLICATION

We have applied to the Listing Committee for the listing of, and permission to deal in, the Shares in issue (including the Shares on conversion of Preference Shares and after the Share Subdivision) and to be issued pursuant to (i) the Global Offering; (ii) the Over-allotment Option; and (iii) the Pre-IPO Stock Incentive Plans and the Post-IPO Share Schemes.

4 STRUCTURE OF THE GLOBAL OFFERING

The Global Offering comprises:

• the Hong Kong Public Offering of initially 22,640,500 Offer Shares (subject to adjustment) in Hong Kong, representing 10% of the total number of Offer Shares initially available under the Global Offering; and

• the International Offering of initially 203,764,500 Offer Shares (subject to adjustment and the Over-allotment Option), representing 90% of the total number of Offer Shares initially available under the Global Offering.

The allocation of the Offer Shares between the Hong Kong Public Offering and the International Offering will be subject to reallocation as described in the section headed “Structure of the Global Offering” in the Prospectus.

In particular, subject to the requirements under Practice Note 18 of the Listing Rules and Guidance Letter HKEX-GL91-18, the Joint Global Coordinators may, at their sole discretion, reallocate Offer Shares from the International Offering to the Hong Kong Public Offering to satisfy valid applications under the Hong Kong Public Offering. In accordance with Guidance Letter HKEX-GL91-18 issued by the Stock Exchange, if such reallocation is done other than pursuant to Practice Note 18 of the Listing Rules, the maximum total number of Offer Shares that may be reallocated to the Hong Kong Public Offering following such reallocation shall not exceed 22,640,500 Offer Shares, representing 10% of the Offer Shares initially available under the Global Offering (before any exercise of the Over-allotment Option), so that the total number of Offer Shares available under the Hong Kong Public Offering will be 45,281,000 Offer Shares, representing 20% of the Offer Shares initially available under the Global Offering (before any exercise of the Over-allotment Option), and the final Offer Price shall be fixed at HK$8.60 per Offer Share (being the low-end of the Offer Price range stated in the Prospectus).

In connection with the Global Offering and pursuant to the International Underwriting Agreement, the Company is expected to grant the Over-allotment Option to the International Underwriters, exercisable by the Joint Global Coordinators (for themselves and on behalf of the International Underwriters) at any time within 30 days from the last day for lodging applications under the Hong Kong Public Offering, to require the Company to issue and allot up to an aggregate of 33,960,500 additional Shares, representing approximately 15% of the Offer Shares initially available under the Global Offering, at the Offer Price to cover over-allocations in the International Offering. In the event the Over-allotment Option is exercised, we will make an announcement which will be posted on the website of the Hong Kong Stock Exchange (www.hkexnews.hk) and on our website (www.kindstar.com.cn), respectively.

5 PRICING

The Offer Price will not be more than HK$9.78 per Offer Share and is expected to be not less than HK$8.60 per Offer Share, unless otherwise announced as further explained in the section headed “Structure of the Global Offering” in the Prospectus. Applicants under the Hong Kong Public Offering must pay, on application, the maximum Offer Price of HK$9.78 per Offer Share plus brokerage of 1.0%, SFC transaction levy of 0.0027% and the Stock Exchange trading fee of 0.005%, subject to refund if the Offer Price as finally determined is less than HK$9.78 per Offer Share.
